Wholetones music to help participants sleep. Data collected after listening to the Wholetones music was compared to that collected both at Baseline, and after listening to the other music condition (i.e. Classical music).

Wholetones® 2Sleep is music that is designed to lull the listener into a deep, delta sleep, using frequency-enhanced music and precise tempos. Wholetones® differs from other musical genres in that it employs a proprietary method of tuning and layering the music with a unique frequency underlayment.

Classical music was the additional music condition used to compare to both Baseline data and Wholetones data.

The classical music was selected based on the Mayo Clinic and NIH music recommendations for better sleep. More specifically, the classical music consisted of the following six pieces: Beethoven (i.e., Moonlight Sonata, first movement), Marconi Union (i.e., Weightless), Chopin (i.e., Nocturne No.2, Op.9), Ravel (i.e., Piano Concerto in G major, 2nd movement), and J.S. Bach (i.e., Prelude No.1).

Participants listened to the Wholetones music for 10 nights consecutively. Participants began playing the music 30 minutes before going to bed and were asked to allow it to play continuously throughout the night.

Self report data used to determine how well participants perceived their sleep quality at Day 0 (baseline), Day 17 (after first music condition Wholetones or classical), and Day 31 (after alternate music condition). This survey consists of 9 total items (some items have sub questions i.e. item 4 which has parts A and B). Scores are calculated as per survey instructions. Any scores of 5 or above indicate poor perceived sleep quality.

Self report data used to determine the perceived mood of participants at Day 0 (baseline), Day 17 (after first music condition Wholetones or classical), and Day 31 (after alternate music condition). This questionnaire has 65 total items and responses are calculated by scoring question responses on a Likert scale fro 0-4, where 0= not at all and 4= extremely. Total numeric scores are determined for the 6 sub scales represented in the survey (i.e. depression, anger, vigor, confusion, tension, and anger) based on which category the item represents. These sub scale scores are then tallied to determine and overall mood score, where higher scores indicate higher levels of depression, anger, tension, confusion, and fatigue. Being that vigor is a positive indicator for mood, these items are reverse scored before being tallied.

Self report data used to determine the perceived anxiety levels of participants at Day 0 (baseline), Day 17 (after first music condition Wholetones or classical), and Day 31 (after alternate music condition). This survey has 20 total items, and responses are scored on a Likert scale of 1-4 where 1=almost never and 4=almost always. Any items that are positive are reverse scored before totaling all 20 items. Higher scores indicate higher levels of perceived anxiety.
